A study on novel photonic devices based on magneto photonic crystal with absolute photonic bandgap

为了实现超紧凑光子电路器件，本研究提出了同时支持TE波和TM波的具有绝对光子带隙的光子晶体波导。在这些波导中，TE波和TM波都实现了单模传播。利用这些波导和磁光子材料，研究了非互易光子晶体器件。此外，还提出了磁光子晶体波导的优化方法，并利用该方法设计了光子环行器。

In this study, in order to realize ultra compact photonic circuit devices, photonic crystal waveguides with absolute photonic bandgap, which can support both TE and TM waves, are proposed. In these waveguides, single mode propagation is realized for both TE and TM waves. Using these waveguides and magneto photonic materials, nonreciprocal photonic crystal devices are investigated. Furthermore, the optimization method for magneto photonic crystal waveguides is also developed and photonic circulator is designed utilizing it.
